2 ) Remove the clamp from the box and band the clamp onto the arm using
3/4" to 1-1/4" heavy duty stainless steel bands (not included) and apply the
following: (See Figure 2)
b) The Valmont® “V”on the clamp should be right side up.
c) Using a level on the at surface where the Valmont “V” is embossed
(b), check that the TR1 Clamp is plumb vertically (0 +/- 1 degree) from
the axis of the arm before tightening the bands.
Band the clamp as close to the free end of the mast arm, not to exceed
5 feet, to ensure the best vibration dampening performance. If there
is a trafc signal or sign located toward the end of the mast arm, you
might want to consider hiding the damper behind it.

3 ) After banding the clamp to the arm:
b) Loosen set screw above the Valmont®“V”.
c) Loosen two hex head bolts. (Note: The TR1 Clamp should now rotate
within its set range of motion.)
Loosen all four socket head cap screws until you reach a 3/4" gap in the
clamp halves (as indicated
in Figure 3). Be sure that the nuts do not back
off of the screws.

4 ) Insert the TR1 damper into the TR1 Clamp from the bottom, until IT IS
within 8"of the center of the damper tube.
(See Figure 4)
(Note: Be sure that you insert the TR1 Damper into the TR1 Clamp taking note
of the direction indicated on the sticker of the Damper, as shown in gure 4.)
b) Tighten set screw above the Valmont® “V” to snug, then an additional
1/4 turn.
Tighten all four socket head cap screws to hold the TR1 Damper in place,
making sure to maintain an even gap on both sides of the TR1 Clamp.
Tighten until snug, then an additional 1/2 turn of each screw.
CAUTION: Do not overtighten and ovalize the TR1 Damper tube. This will
cause the TR1 Damper to NOT function properly.

6 ) check that the TR1 Damper is within 1 degree of plumb in all directions.
After installation is complete, check the casing for objects magnetically
attached to the TR1 Damper. If any, remove these objects which will
render the TR1 Damper ineffective.
5 ) Rotate the TR1 Clamp to be plumb vertically (0 +/- 1 degree), and tighten
the two hex head bolts to snug, then an additional 3/8 turn.
(See Figure 5)
(Note: Using the indexing to assist in nding level, and to hold position
when tightening.)
